330 tire motorcycle swingarm kits are bolt on replacements for the stock 1991-99 Harley Softail swing arms and they enable you to mount a 330 tire on your stock Evolution Softail without doing any modifications to the frame.

These 330 tire motorcycle swingarm kits can be installed only in conjunction with a 20mm secondary belt and can fit up to 12” wide rims. Thanks to this innovative wide swingarm you will be able to mount a super-wide rear tire, without any modifications to your stock frame, still keeping front and rear wheels properly lined up for safe riding and great handling.
